We bought a brand new Intex Sand Filter to use with our above ground pool starting this year and have run into the difficulty of figuring out how to connect the hoses that came with the filter to the valve and to an existing hose. See pic for reference. All hose openings are 1.5". I don't have the valve opening measurement itself but pretty certain a 1.5" is what fits inside. Any ideas on how to make these connections possible would be great.
